• You are probably not forcing the "Liberty" GTK theme (the Mer default), which is why my display looks different than yours. I use the Liberty theme and run the sapwood theme server.
• I haven't tried installing Synaptic.
• easy-chroot 0.1.7 is all about low level clean-up and hooks for future features, it shouldn't noticably impact anything higher-up (yet). Wait till my new Easy Ubuntu / Mer package(s) come out, all the cool new stuff I'm building into easy-chroot (like auto-running scripts when you open a chroot) will suddenly come into effect.*
• You will have to run xmodmap manually, since I only ran it as part of LXDE setup.

*You can start using the autorun scripts now, if you want; this would probably be good if you want to run sapwood or xmodmap when you start up your Mer/Ubuntu chroot (substitute $CHROOT with your mountpoint):

$CHROOT/var/run/onfirstchroot-ext.rc

This script will run commands as root in maemo the first time you "open" a chroot. So this is where you could force the processor to "performance mode" or some such thing.

$CHROOT/var/run/onfirstchroot.rc

This script will run commands as root in the chroot the first time you "open" a chroot. This is where you'd put xmodmap and sapwood-server. Note that you want to run both of these as "user", so see below.

$CHROOT/var/run/onchroot-ext.rc

This script will run commands as root in maemo every time you run a chroot command.

$CHROOT/var/run/onchroot.rc

This script will run commands as root in the chroot every time you run a chroot command.

Note that all of these scripts need to be marked executable. If you want to run a command in one of these scripts as "user", you need to preface the command with "su user -c", eg "su user -c xmodmap /home/user/.Xmodmap-keymap"
